Good examples andy!
Although these gestures are done in acting, there is no experience like getting it from the real thing (or person) at the time and occasion.
Good general ideas of deciphering people's body language are shown here but for us Aspies, learning it is a scientific process and also from getting to know the new stranger in your life as the person s/he is over an extended period of time.
For me, deciphering body language remains much a puzzle to me until I've known the person over at least 2 years. Otherwise, I rely on an intuition developed over my decades of having lived with AS and coming to my acceptance of the same at a late time in my life.
I am pleased to announce that my own social successes have gotten better over these past few years.
